Abstract

A novel miniature ultrawideband antenna is proposed that exhibits excellent radiation characteristics. The antenna is based on the simplified composite right/left-handed transmission-lines (SCRLH-TLs) that are implemented using F-shaped and T-shaped slits on the antenna's ground-plane and radiating arms, respectively. The coplanar waveguide feed-line is impedance matched to the radiating patches using H-shaped microstrip stub. The antenna operates between 0.65 and 9.2 GHz, which corresponds to an impedance bandwidth of 173.6%. The maximum gain and efficiency measured are 3.5 dBi and 70% at 4.5 GHz, respectively. The antenna dimensions are 25 × 15 × 1.6 mm³ or 0.054λ₀×0.032λ₀×0.003λ₀, where λ₀ is free-space wavelengths at 0.65 GHz.
